perlfunc Describes both chop and chomp, with good examples and excellent detailed explanations.
I downvoted the tutorial, because it adds nothing to the existing documentation and thus only makes things harder for beginners.

  1. Why did you use $a instead of $_?
  2. print Doesn't return it's given attributes, it returns true if succesful. All your "would return" comments are wrong.
  3. You didn't even chomp arrays or hashes.
